Solution Overview

Problem

Current methods for data transmission from or into a borehole or milling slot are unreliable due to the susceptibility of plug connections and require data lines, which are prone to malfunctions and damage, especially in harsh drilling operations, and wireless transmission is hindered by filling materials.

Innovation Solution

The use of an electrically conductive body with a processing device and transmitting/receiving units that emit/receive high-frequency signals, allowing for signal transmission through the conductive body and eliminating the need for data lines, plug connections, and complex couplings, even in filled holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If plug connections are used to connect data lines between rod sections, then data transmission can be achieved, but the system becomes unreliable due to susceptibility to failure and damage in harsh drilling conditions

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoiddata line connection complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the data transmission function from the mechanical connection system by using the drill rod itself as the transmission medium. Instead of separate data lines with plug connections, the electrical signal is transmitted through the drill rod's metallic body, eliminating the need for separate data transmission components and their vulnerable connections.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The drill rod serves multiple functions: it provides mechanical support for drilling operations and simultaneously acts as an electrical transmission medium for data communication. This multi-functionality eliminates the need for separate data lines, reducing system complexity and potential failure points while improving reliability in harsh drilling environments.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If data lines are used for data transmission, then data can be transmitted from the borehole, but the data lines are prone to malfunctions and damage in harsh drilling operations

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidmaintenance requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent removes the separate data line component from the system by utilizing the drill rod's metallic body for signal transmission. This extraction eliminates the data line's vulnerability to damage and malfunction, thereby improving reliability and reducing maintenance requirements in harsh drilling conditions.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If wireless transmission is used, then data transmission without physical connections is achieved, but the filling material in the borehole significantly impedes electromagnetic wave propagation

Engineering Contradiction:
Improveconnection complexityVSAvoidsignal transmission reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent uses the drill rod's metallic body as an intermediary medium for signal transmission. Instead of relying on electromagnetic waves that are blocked by the filling material, the electrical signal travels through the conductive drill rod, which penetrates the filling material without being impeded by it, thus maintaining signal reliability while avoiding complex wireless transmission through the barrier.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If induction coils or contacts are used to connect rod sections for data transmission, then data transmission between sections is achieved, but the system becomes complex and vulnerable to failure

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidcoupling mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the data transmission function with the drill rod's structural body. Instead of adding separate induction coils or contacts to connect rod sections, the electrical signal is transmitted through the continuous metallic body of the drill rod itself, simplifying the system by eliminating additional coupling mechanisms and their associated complexity and failure points.

Inventive Principle:
Principle #5Merging (Combining)
